A lift buffering structure includes a hollow column-shaped housing, a holding seat fixedly connected to an inner wall surface of the hollow column-shaped housing, an inner stem disposed in the hollow column-shaped housing and slidably extended through the holding seat, an elastic element having an end connected to the inner stem and another end to the holding seat to limit a travel stroke of the inner stem, an abutting unit disposed at one side of the holding seat opposite to the elastic element and having a width downward reduced gradually along a height direction of the hollow column-shaped housing, and an anti-slip unit connected to a lower end of the inner stem and located between the abutting unit and the inner wall surface of the hollow column-shaped housing. The lift buffering structure having the above structure can overcome a lot of problems in the conventional gas and oil struts.

A support prong system for a laptop device or other device includes one or more support prongs that are attachable to an underside of the device. Each support prong has a proximal prong portion for attachment nearest the device, and a most distal portion for contact with a device supporting surface. The support prongs may include one or more intermediate prong portions between the proximal prong portion and most distal portion. The system includes an attachable mount typically attached to the underside of the device and residing between the proximal prong portion and the device. The attachable mount has an active coupler member that couples and decouples with the proximal prong portion. Height and angle adjustment for the laptop or other device may be obtained by adjusting the one or more support prongs.

An autonomous mobile device has a tower extending from a main body. The tower pans from left to right. An extensible mast may extend through, and pan with, the tower. An upper section is attached to the tower by a hinge and may tilt with respect to the tower. The upper section may include a touchscreen or other devices. An assembly with separate pan and tilt motors allows for the tower and attached upper section to pan while also allowing the upper section to tilt independently of the panning motion. The tilt motor is within the portion of the assembly rotated by the pan motor. The tilt motor drives a worm gear in the tower to rotate a tilt axle. An asymmetric friction hinge connects to the upper section to the tilt axle. Rotating the tilt motor rotates the worm gear, rotating the tilt axle and the attached upper section.

A stand assembly and method of converting a stand assembly from a moveable configuration to a stationary configuration is provided. The stand assembly includes a plurality of wheel assemblies slidably engaged with a plurality of respective trivets, each wheel assembly being moveable between a stowed configuration and a deployed configuration, thereby moving each trivet between a deployed configuration and a stowed configuration, respectively. When in their respective deployed configurations, a distal end of each trivet is engaged with the floor, thereby causing the stand assembly to be in the stationary configuration. When in their respective stowed configurations, the distal end of each trivet is positioned between two wheels of the wheel assembly such that the wheel assembly prevents the trivet from engaging with objects on the floor, thereby minimizing adjustments required to obtain desired ground clearance.

A joint portion for angle adjustment arranged between a leg base portion and a leg support member of an imaging equipment-grade tripod includes a joint fixation member with a joint, a pole member having an upper end connected by the joint of the joint fixation member a lower end connected to the leg base portion, a sleeve provided below the joint fixation member and fitting to the joint fixation member, and a coil spring wound around a central axis of the pole member and pressing the sleeve upward. With the joint portion being fixed by fitting between the joint fixation member and the sleeve, the sleeve is pressed downward to release the fitting between the joint fixation member and the sleeve, so that the joint portion is released.

A telescopic support includes a positioning device, a panel fixing member, two fixed rods, and two lifting rods. One ends of the two lifting rods are equipped on both sides of the panel fixing member, and the other ends thereof rods are plugged into the corresponding fixed rods and move in an axial direction of the fixed rods. During the lifting process of the lifting rods, the relative positions between the lifting rods and the fixed rods are maintained via the positioning device.
